A system designed to assist training managers or evaluators in increasing the effectiveness of military training programs has been developed, tested, and refined. The Training Program Evaluation (TPE) system offers advantages over traditional approaches of assessing program effectiveness. TPE involves the direct observation of training and testing and does not rely on second-hand accounts of training given by trainers or trainees. Neither does TPE require the construction and administration of specially designed tests to evaluate soldier performance, but uses instead the tests routinely given after each block of instruction. During its development, TPE was frequently field tested to determine its utility to the Army. The major test of TPE came during the M1 tank Operational Testing Cycle III (OT-III), where TPE was used to evaluate the effectiveness of the M1 transition training program and to suggest program improvements. The utility of TPE was demonstrated during the M1 OT-III, where several agencies used TPE to gather training effectiveness information that was used to improve the training program. Lessons learned during the field testing of TPE have been incorporated into the TPE system, resulting in a useful product. (Author/KC)
